A New Testament prophet is not quite like an OT one. There is no exclusivity for one thing. Many people receive revelation from God...so then church should be open to allow freedom of expression in the assembly.
Since there is no exclusivity...other members who also received revelation can confirm or deny what was previously prophesied.
So we are to encourage prophecy...but with correction in place from other "prophets."
Oversight in the church is not to shut people down...but to free them up and encourage them to open their hearts and minds to God. As long as there is good order...the church leadership should just sit back and pray. The prophets are subject to the prophets.
Let the Body function.
If the members are too immature to listen to what God is saying...THEN, oversight needs to regulate and correct the lack of spiritual discernment in the members. This is meant to get people back on track...not discourage them from further revelations from God...as what normally happens.
Love believes and hopes all things...yes, even the spiritual growth of the church!
